Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage fl oor. The safety reversing sensors must be connected and aligned correctly before the garage door opener will move in the down direction. When the light beam is obstructed or misaligned while the door is closing, the door will reverse and the garage door opener lights will fl ash ten times. If the door is already open, it will not close. The sensors can be aligned by loosening the wing nuts, aligning the sensors, and tightening the wing nuts. Check to make sure the LEDs in both sensors are glowing steadily. The LEDs in both sensors will glow steadily if they are aligned and wired correctly.

Adjustment Introduction Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system. After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" (3.8 cm) high object (or 2x4 laid fl at) on fl oor. Your garage door opener is designed with electronic controls to make setup and adjustments easy. The adjustments allow you to program where the door will stop in the open (UP) and close (DOWN) position. The electronic controls sense the amount of force required to open and close the door. NOTE: If anything interferes with the door s upward travel it will stop. If anything interferes with the door s downward travel, it will reverse. To prevent damage to vehicles, be sure fully open door provides adequate clearance. Programming Buttons The programming buttons are located on the left side panel of the garage door opener and are used to program the travel. UP Button Adjustment Button DOWN Button 11

Adjustment 2 Test the Safety Reversal System 3 Test the Protector System Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. Safety reversal system MUST be tested every month. After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on contact with 1-1/2" high (3.8 cm) object (or 2x4 laid fl at) on the fl oor. Without a properly installed safety reversing sensor, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door. 3.1 Open the door. Place the garage door opener carton in the path of the door. 2.1 With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid fl at) on the fl oor, centered under the garage door. 3.2 Press the remote control push button to close the door. The door will not move more than an inch (2.5 cm), and the garage door opener lights will fl ash 10 times. 2.2 Press the remote control push button to close the door. The door MUST reverse when it makes contact with the board. The garage door opener will not close from a remote control if the LED in either safety reversing sensor is off (alerting you to the fact that the sensor is misaligned or obstructed). If the garage door opener closes the door when the safety reversing sensor is obstructed (and the sensors are no more than 6 inches [15 cm] above the fl oor), call for a trained door systems technician. If the door stops and does not reverse on the obstruction, increase the down travel (see Adjustment Step 1). Repeat the test. When the door reverses upon contact with the 1-1/2 inch board, remove the board and open/close the door 3 or 4 times to test the adjustment. If the test continues to fail, call a trained door systems technician. 13
